Favero Power Meters

Favero makes one of the most popular power meters we sell – the Assioma power meter pedal. If you use LOOK Keo cleats, they offer the DUO and the UNO. With both versions, you get both a left and right pedal. However, the DUO has a power sensor in each pedal and measures left and right leg power. The UNO has a sensor in only the left pedal and measures left leg power.

If you prefer Shimano SPL-SL cleats, they offer the DUO-Shi power meter spindles. With the DUO-Shi spindles, you insert them into your existing Shimano pedal bodies. The DUO-Shi only comes in a dual-sided version. Favero power meters are the most affordable power meter pedal. In addition, they are accurate to within 1.0%, use a rechargeable battery, Bluetooth SMART and have a great track record of reliability.

Installation

Both the Assioma DUO and UNO are a breeze to install. Simply grab an 8 mm hex wrench and screw them on – just like a normal pedal. The DUO-Shi takes a bit more work as you need to first install the spindles into your Shimano pedal bodies, but it is a relatively simple process. These power meters can also be moved between bikes quickly and easily.

Before the first ride, Favero power meters do have some one-time set-up steps such as registering them with the app taking a quick ride to set the installation angles. Its easy stuff and is outlined in the manual so be sure to give it a quick read.

Weight

Favero power meters are the lightest power meter pedals available. The DUO and the UNO weigh in at 149.5 grams per pedal. The DUO-Shi weighs 157 grams in a Shimano PD-R8000 pedal body. This is only slightly heavier than a standard road pedal.

Power Measurement

The Assioma DUO and DUO-Shi measure power from both legs as well as independent left/right leg power. This means it can tell you how much power each leg is producing individually. The Assioma UNO measures left leg power and like all left-side power meters, doubles the left leg value to give you total power.

Special Features

The Favero power meters are the only ones with IAV (Instantaneous Angular Velocity) Power. This special software and integrated three-axis gyroscope results in accuracy of +/- 1.0%. In addition, IAV allows you to use the pedals with oval chainrings without any impact to the accuracy of your data.

Batteries

Favero power meters use rechargeable lithium-ion batteries. Battery life is around the 50-hour mark, which is good for this type of battery.

Communication Protocol

Favero power meters transmit data via both the ANT+ and Bluetooth SMART wireless protocols. Therefore, they are compatible with just about any bike computer. You can also use a smart phone or tablet as your head unit.

Accuracy

Featuring IAV Power Technology, Favero power meters are accurate to within +/- 1.0%. This is on par (to slightly better) than the majority of other power meters on the market.

Cadence Detection

Like most power meters, the Assioma DUO, DUO-Shi and UNO use an accelerometer to measure cadence. This means you don’t have to worry about attaching a magnet to your frame.

Warranty

Favero power meters come with a two-year manufacturer’s warranty.
